Deployment History
Vulcan keeps a record of your app's deployments so you can see how it's evolved and roll back if needed.
What's tracked
Each time your app deploys (preview or production), Vulcan records:
- When it deployed
- What changed (file additions, edits, deletions)
- Whether the deployment succeeded or failed
- Build output and timing
Viewing deployment history
Open the Deployments panel inside your project to see the history. Each entry shows the timestamp and deployment status.
Automatic version snapshots
Every successful production deploy automatically saves a version snapshot. This means you always have a rollback point without manually saving versions yourself.
For example, if you deploy to production and then the next day's changes break something, you can restore the snapshot from the previous production deploy.
Build failures
If a deploy fails (e.g. there's a code error), you'll see the failure in the chat with the build log. The previous working version of your app stays live — a failed deploy never takes your app offline.
The AI will usually catch and explain the error. Describe what you were trying to do and it will fix it.
Rolling back a deployment
To go back to a previous working state:
- Open Versions in your project
- Find the snapshot you want to restore
- Click Restore
- Deploy to production to push the restored version live
